HUB-BEARING.

Application filed May 3, 1920.

To all whom it may concern Be it known that l, TRUMAN l3. FUNK, a citizen of the United States, residing at ll/loline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Hubddearings of which the following is a specification.

The present invention has to do with certain improvements in bearings. The invention has reference particularly to the construction and arrangement of parts which are lubricated by means of oil or lubricant circulated under pressure. The features of the invention are very well adapted for use in bearings for automobile fans and thelike, although it will resently appear that the features of the invention also be used in other locations and for lubrication of other bearings. Neverthe less, inasmuch as the features of the in vention are especially well adapted for lubrication of automobile tan bearings, I have illustrated the invention and will describe the same as being applied to this particular type of bearing.

One of the objects of the present invention is to provide a bearing of very simple construction and one which can be made cheaply and from a minimum number of parts.

Another object of the invention is to provide a bearing for fans ,and the like, which will be self-contained, and of which the parts are so formed that they can be very easily cast and put through the various manufacturing operations.

Other objects and uses of the invention will appear from a detailed description of the same which consists in the features o'l construction and combinations of parts hereinafter described and claimed.

Fig. 9 shows a detailed section taken on the line 9-9 of Fig.5, looking in the direction of the arrows.

I will first describe the construction shown in detail in 1 to at inclusive.

In this case, there is provided a stud or pin 10, the end portion 01" which is lined to a stationary part such asthe engine trains, and the body portion of which serves as a shaft or support for the hearing. The body portion of the bearing comprises an inner sleeve 12 which seats directly upon the pin 1G. and an outer shell member 13 which encircles but is spaced away trorn said sleeve. The shell member 13 tapers from its inner end 14 to its outer peripheral portion 15, the inner end 14- being drawn inwardly and closely encircling the stud or pin 10.

A series of separated lugs 16 are provided on the inner end of the sleeve 12 (only one oi said lugs appearing in F 1). These lugs serve to :lurther support the inner end oi the shell 13 while permitting oil or lubricant to circulate ireely past the lugs. The outer end of the sleeve 12 is flared outward to provide a flange 17'; and the out-er end 15 of the shell 13 seats against the periphery of said flange to which it may be socured in any suitable manner. This arrangenient serves to inclose an oil space or chamber 18 between the sleeve and shell, and a plug 19 may be used to close an opening through which said chamber may be filled from time to time. A pulley flange 20 may be formed integral with the shell 13, as clearly evident from Fig. 1.

in the outer face ot the flange portion 17 may be provided a circular recess 21 concentric with the stud or pin 10, and a hole number of parts.

22 is formed at the center of said recess to receive the end portion of said stud or pin. Another circular recess 23 is formed in the outer face of the flange 17 and merges segmentally with the recess 21. An oil perforation 261- extends through the flan e from the recess 23 to the inner or back face of the flange; and a slotted recess 25 extends between the

circular recesses

21 and 23 at the point where the teeth of gears operating or located in said recesses-will mesh.

On the end of the stud or pin 10, or f rmed integrally therewith, as desired, is a gear 26, the'teeth of which closely engage the circular wall of the recess. A pinion 27 is located within the recess 23 and its teeth closely en 'age the wall of said recess, and also mesh with the teeth of the gear 26. The pinion 27 is mounted on a stud 28 in the flange 17. The arrangement is such that oil drawn through the perforation 2 1 will be carried around by the teeth of the pinion 27 to the point where the teeth of the pinion and gear come together, and will then be forced down through the slotted passage 25 and against the stud or pin 10. Said oil will then be compelled to travel along the stud or pin and lubricate the same. It will finally work its way through and be delivered adjacent the inner end 14c of the shell. A fan plate 29'seats over and is secured to the flange 17 and carries the fan blades 30, if the same be used. This plate 29 also closely engages the gear and pinion aforesaid so as to insure the flow of oil in the manner just explained.

It will be observed from an examination of this construction that it makes use of parts which may be very easily cast in molds of very simple forms, and from a minimum It will also be observed that this construction involves the use of a sleeve seated directly upon the stud or pin,

I and having its outer end flanged in conjunction with an encircling shell which engages the peripheral portion of said flange.

Referring now to the construction shown in Figs. 5 to 9 inclusive, the same is a modilication of that just described in detail. In this present case, the sleeve 12 has its inner end 31 carried beyond the inner end 14 of the shell 13, so that said inner end 14 is directly supported by the sleeve 12. Furthermore, a groove 32 is provided encircling the inner face of the sleeve 12 adjacent 1 to the inner end 31 thereof so as to collect the oil flowing along the stud or pin and deliver the same into the space or chamber 18 through the medium of a series of openings 33. It is also observed that on the inner face of the shell 13 adjacent to its outer end 15 ther is provided an encircling groove 34 for the purpose of insuring a perfect seal between said outer end 15 and the flanged portion 17. It is also observed that the lugs 16 of the arrangement shown in Figs. 1, 2, 3, and 1, are dispensed with in the present case, since the inner end of the shell is directly supported by the inner end of the sleeve.

While I have herein shown and described certain embodiments of my present invention, still I do not limit myself to the said embodiments except as may do so in the claims.

I claim: 1. A pressure lubricated bearing comprising, in combination, a stationary stud, a sleeve journaled thereon, an outshzndhig flange at the outer end of said sleeve, a concentric shell surrounding said sleeve and spaced away therefrom to provide an annular oil space, the inner end of the shell being supported by the inner end of the sleeve, and the outer end of the shell hein in engagement with the peripheral portion of the sleeve flange to inclosc the oil space aforesaid, there being a circular recess in the outer face of the sleeve flange concentric with respect to the stud, a gear located in said recess and rigid with respect to the stud, there being another circular recess in the outer face of the sleeve flange and in peripheral communication with the first mentioned recess, a pinion rotatably mounted in the second mentioned recess. a cover plate extending over the gear and pinion and said recesses and serving, in conjuuctimi with the sleeve flange, to inclosc said rccesses, there being an oil passage extending through the sleeve flange and establishing communication betweeu thc oil space and the path of travel of the pinion teeth. and there being another recess establishing communication between the point of ennies n ment of the teeth of the pinion and ge and the end of the stud, suhstautiall. described.
